The Dread Necromancer is a complete reimagining of Necromancer - while it shares many of the themes and names, and has a few talents retained, it's effectively an entirely new take on the class.
It still uses mana and souls, but souls behave quite differently. You can store up to 5, and regenerate and can retain up to 3 out of combat. Damage dealt by you and your minions grant soul fragments, and you gain a soul when you obtain a sufficient amount. Souls are used both to summon minions, and for your more powerful spells.
Depending on your categories chosen you can have powerful, temporary minions, weaker mass minions that last indefinitely in combat, or a single minion with customization options.

One year has passed since the one the Orcs call the "Scourge from the West" came and single-handedly crushed the Orc Prides of Grushnak, Vor, Gorbat, and Rak'Shor.  The Allied Kingdoms, now linked by farportal to their distant, long-lost Sunwall allies, have helped them conquer most of Var'Eyal.  The few remnants of the ravaged Prides are caged...  but one Pride remains.  Kruk Pride, isolated on an island, is the last orcish settlement that stands; they, too, face their impending doom.  The Sunwall has blockaded the only exit point from the island, and now, the technologically advanced civilization of Steam Giants have come down from the mountains to take their homeland with machines and weaponry unlike anything else on Eyal.  Kruk Pride has reverse-engineered their technology before; their only hope is to do it again and rise up against the Pride's foes.
 

Features:

• Explore a whole new campaign from level 1 to 50, one year after the events of the original Tales of Maj'Eyal campaign. Liberate the Orcs (or die trying) by rising up against the Sunwall, the Steam Giants of Atmos, and other dangers that may lie in wait...
• Play as one of three new races: the battle-hardened Orcs, the brutal Yetis, and the unstoppable Whitehooves. Discover their stories, their pains, their hopes... and their awesome racial powers!
• Risk your life in over 20 unique zones! Explore the ruins of a lost city, lay siege to the Sunwall forces at the Gates of Morning, and raid the Steam Giants' mining quarry - each has its own unique foes and hazards, leading each to feel and play different from the others.
• Play as one of the four new tinker classes: Gunslingers, Sawbutchers, Psyshots and Annihilators! Plus a class evolution: Technomancers! Crush and rend your foes with heavy metal, electrocute and immolate them with your gadgets, charge across the battlefield or nimbly strafe in style - each plays differently, and none provide any shortage of ways to slay your foes.
• Master steam technology to build powerful tinkers to augment your equipment. Need to close in a bit quicker? Turn your boots into rocket boots! Having a hard time deciding whether to shoot someone or stab them? Build a Hand Cannon into your gloves, or deploy a Weapon Automaton to do the stabbing for you! If you have a problem, steamtech has a solution, usually involving explosions; with over 80 different powerful contraptions to craft, enjoy unparalleled versatility and trying something different with every playthrough.
• Master the tactical uses of over 140 talents! Fire bouncing trick-shots and psychic-infused shots, use your steamsaws as shields or wheels, terrify your foes with long mechanical arms - there are no "boring" talents here, everything has its own special applications and properties!
• Use advanced technology in the world of Eyal! Burrow through sand, plant bombs to destroy tunnels, and discover that you aren't alone in using it...
• Infusions and runes are for puny humans; implant new medical injectors to pump an array of experimental chemicals into your body! Injectors can use any (infinitely reusable) salve in your inventory as long as they're off their cooldown, giving you versatility you've wished you could get with a couple of inscriptions.
• Loot over 70 new and powerful artifacts. Pump lead into foes with big guns, quick guns, and explosive guns! Shred them with saws that maim, saws that thirst for blood, and saws that aren't really saws! Violate common sense by strapping a rocket to your back and calling it a jetpack!
• Enjoy dying in horrible and exotic ways at the hands (or claws, jaws, guns...) of over 140 new creatures! Not mere piles of stats and chain-stuns, these foes will provide unique challenges - suffer the Sunwall's newest cosmic spells, the new breeds of ritches that infest and multiply, the Steam Giants' elaborate defense systems, and find new strategies to adapt to each!
• Earn a trunkload of achievements! Have your accomplishments recognized for liberating the Orcish people, displaying exceptional mercy or cruelty, or showing your prowess with impressive feats! Give a boss a fate worse than death, show Sunwall forces how frustrating it is to fight a Radiant Horror as a paladin, come out on top against impossible odds, display a suicidal lack of situational awareness, and wear a badge of pride or shame for each!
• Read roughly 27,000 words of new lore to immerse yourself in the world! Learn how things have changed since the Scourge's campaign, feel hatred and/or pity for your foes, uncover grand schemes and sinister plots, and notice the elaborate connections between Var'Eyal's numerous factions. Every zone has a story behind it, and every story ties into a bigger picture; enjoy a tale of horror and humor, of intrigue and glory, of despair and hope.
• Earn the right to use the classic (and Ashes of Urh'Rok) classes in Embers of Rage, and the new tinker classes in Maj'Eyal! Play a Brawler in the East to fulfill your life-long dream of suplexing an entire nation of giants, or play a Sawbutcher in Maj'Eyal to shred through Dreadfell in a whirlwind of sawblades and steam!

This is a patch for addons with 'archery' talents that have not been updated since the 1.6.4 change to archerPreUse .

Assuming they were still functioning as of 1.6.3, this patch should allow them to function once again. I can confirm this works with both Zephyr and Viper class addons, but I have not tested it further.

Save files which have been affected by this change will cause the game to flash black and freeze, as will attempting to create a new character that would learn an affected talent at birth, or when learning an affected talent later on, or when an enemy spawns with an affected talent. There will be no error pop-up in game if this happens, but the error can still be found in te4_log.txt and should be repeated many times at the end of the file. If you see an error that refers to an addon and archerPreUse, this patch should solve the issue.

This is a stand-alone Quality of Life pack that improves some minor things about ToME gameplay.
This pack makes size categories VISIBLY apparant. To be clearer-- A "Tiny" ant will now look SIGNIFICANTLY smaller than, say... A "Big" bear.
Background: I know-- It's so obvious, right?? For the longest time, I've wanted to make this add-on-- But it was only now that I could confirm its stability.
Stability: Very High

Many in Maj'Eyal have heard of "demons", sadistic creatures who appear seemingly from nowhere, leaving a trail of suffering and destruction whereever they go. Their Fearscape floats far above the skies, watching and waiting, but not idly; their agents scout the land, their legions build up their forces, and their scholars develop new spells and strategies. As the barrier between our worlds begins to crack under their scrutiny, helpless Eyalites have begun to disappear, whisked up to serve as their slaves and playthings. They imbue these victims with magical powers to better survive the ensuing stresses - can you use your new-found abilities to escape the legions of Mal'Rok?

Features:

• Start with a new class, the Doombringer! These avatars of demonic destruction charge into battle with massive two-handed weapons, cutting swaths of firey devastation through hordes of opponents. Armed with flame magic and demonic strength, they delight in fighting against overwhelming odds, softening up the crowd with waves of fire, then feeding on the flames and suffering of their surroundings to stay alive while quickly reducing any group to a pile of ash and gore.
• Unlock a new class, the Demonologist, with an all-new item enhancement mechanic! Bearing a shield and the magic of the Spellblaze itself, these melee-fighting casters can grow demonic seeds from their fallen enemies. Imbue these seeds onto your items to gain a wide array of new talents and passive benefits, and summon the demons within them to fight on your side! Ever looked at a gigantic demon-cursed minotaur and wished it was on your side for once? Well, now you CAN summon one to pound your foes into paste while you cast devastating spells from afar, or call forth a squad of Fire Imps to pelt your enemies to death while they exhaust themselves on your impenetrable defenses! Demons have persistent health, making them a little more precious than disposable necromancer skeletons or summoner beasts, but can be revived from death nonetheless.
• Two new zones, with all-new art, foes, and bosses! You've seen the plains of the Fearscape before, now see the lairs and headquarters of the demons themselves!
• Over 10,000 words of written lore to find! The demons were once an enlightened, peaceful race, hailing from a distant planet known as Mal'Rok; learn what drove them to plot Eyal's eternal torture! Discover monuments to each of the demonic species and noteworthy individuals, showing the place of honor each has among them! Get a glimpse into the culture and daily lives of these sadistic invaders and their brainwashed thralls!
• Unlock a new race, Doomelves: Shalore who've taken to the demonic alterations especially well, corrupting their typical abilities into a darker form. Blink away to safety, transform into a shadowy dúathedlen to hide in the shadows or prey on your foes with blasts of darkness, use your new resilience to soak up status effects and critical hits, and assault your enemies' minds to leave them unsteady in combat!
• Between the aforementioned classes and Doomelves, a whopping 75 new talents!
• Unlock two new cosmetic options! You know you've always wanted demon-horns.
• Two new events, appearing anywhere in Eyal!
• 20 new artifacts, with unique and interesting effects. Collect the Obsidian Treasures to amass more and more power! Slip your hands into the Will of Ul'Gruth and watch your sweeping blows smash down walls! Wear a giant hideous hell-mouth as a fashionable belt!
• 7 new achievements! Conquer the worst Urh'Rok's forces can throw at you, and hang their metaphorical skulls from your profile page!

Adds a new game menu option "Show known Landmarks", which presents a list of landmarks (up/down stairs, golden chests, zone entrances and the like) that you've seen on the current level and allows you to go to them or view them on the map.  You can also set your own landmarks for later reference by right-clicking on the map and choosing "Set landmark".

Also available as part of the ZOmnibus Addon Pack and ZOmnibus Lite.

Important: this addon will have no effect if left unconfigured! Please read the description!

Recommended settings:

hit escape -> video options

• Requested FPS: 30
• Resting divider: 10
• Running divider: 5

Description:

Enables faster run/resting by use of FPS dividers.

These dividers simply divide the game's requested FPS by their respective values while resting or running. After starting a new game or loading a saved character, configure this addon by hitting escape -> video options. Setting these dividers to something greater than one can substantially reduce the amount of time required to finish resting/running on older computers.

Just be careful when resting on an escort mission...

Changelog:

See the forum discussion for the changelog.

Adds the Grove Keeper, a Wilder subclass. The Grove Keeper is pirmarily a mindpower-caster with limited summoning ability, but has the option to mix slings, or one-handed weapons and unarmed attacks, into their skill set. They are also able to become proficient with mindstars and focus wholly on mind-casting. Includes advanced class categories favoring either weapon-hybrid or mind-casting play style, with the advanced hybrid tree working equally well for ranged or melee.

Quality of Life improvements for resting and auto-exploring.

v3.5.0 *** FOR ToME v1.6.5 ***
This is a fork (with permission) of Marson's auto-explore and rest tweaks. It includes as well C.Lowe/CaptainTrip's improvements as well. It does not include, but recommends also using Johnny0's Faster RRE add-on for even better rest and auto-explore experience. This add-on contains numerous Quality of Life improvements designed to make resting and auto-exploring easier to use, brings the add-on overall up to being compatible with 1.6.x, and generally seeks to remove it being more optimal to do timed rests or manual recovery (particularly to help higher difficulty level and players without Faster RRE). Cleaned up feature list in this take, to make it easier to see what it does.

It is recommended to turn off Marson's Rest and Auto-Explore as well as C.Lowe's Rest Tweaks if using. This addon is meant to include all of them.

Latest Update Notes:
• Changed steam sustain behavior to match current gameplay. Before sustains tended to shut off when available resource was 0, now they don't seem to do so. This will now only turn off sustains that drain steam if steam is going below 0, so as to get to a steady finish state.
• Fix minor bug where stealth enabling was always on if you had it.
• Added new option to ignore quest members when resting or exploring. It defaults to off but for those folks that know they want to ignore those quest allies and rest a bit.

Existing Features:
• removed First Sighting and Reset on Rest. Someone can patch them in if they'd like it back, but I'm not really keeping them alive.
• Fixed actor bugs causing Elemental Surge to never reset. Thanks Reca♥den.
• Fixed bug with Paradox Spacetime Tuning from 1.5.5. This may rebreak posessors with paradox, hard to kinda test.
• Mostly verified working on 1.6.0
• Compatibility with restart sustains. Thanks zizzo.
• When resting, it will check for infusions and runes that could be used to accelerate HP, Mana, or Equilibrium (via Ancestral Life or Meditation) recovery. If the acceleration appears significant, it will use them, rotating from first available infusion or rune outward. In experiment, I found this often reduced rest turn time by 50-80 percent, improving the more drained the resource was. Particularly helpful for Mana, as it avoids trade-off advantages of short term resting (for increased mana regen) + rune use by just handling that more optimal play for you automatically without breaking rest.
• Support for steam implants, with usual checkboxes. This may not always be faster based on steam sustains that may disable after the initial round of rest and steam implants having very long cooldowns (30+ turns) and steam's resource max being pretty small. It tries to be conservative on that, so will most likely help for cases where your functional steam regen rate is < 2.00 and never activate for things much above it. I found I was often getting 5-20 steam per turn, which makes the implant support useless.
• Supports for medical healing salve injectors. Cooldown measurements are a bit odd here, since they can range from 5-20 depending on injector. Went with 10 as a happy medium for how many turns of natural regen is considered to be equal to the cooldown cost of using it.
• Adding support to auto-stealth if available and not stealthed.
• Option for ignoring small damage when moving and resting, basically if it is <5%, it will ignore it by default, prevent small DoTs from preventing rest.
• Options added to control whether or not to use inscriptions to accelerate recovery of things.
• Fixes a ToME bug that can cause autoexplore or running to move only a single square and hang if used immediately after killing an enemy.
• Lore discovery will only stop autoexplore if it triggers a popup.
• Autoexplore will ignore Exploratory/Infinite Farportal return portals until the entire level has been explored.
• Ignores special terrain features such as Font of Healing after they are first discovered.
• Ignores open chests and alt Maze floor cracks.
• Rest and AE ask for confirmation if you have an escort in your party.
• Ignore already activated pedestals.
• Checks for and waits on any rechargeable items.
• Checks for and reloads any ammo in offhand quiver.
• Waits for cooldowns of talents set to auto-use.
• Waits for depleted air to replenish.
• Combines all checks into a single instance of rest, rather than having cooldowns etc. require a second resting phase.

Determines how auto-explore and running respond to telepathy, including mouse moves. Regardless of the setting, hostiles seen via telepathy will not halt resting or the Rod of Recall, nor trigger automated talents. Unique or powerful monsters (rank > 3) will always trigger a halt to running when they are spotted via telepathy for any mode except 'Original'.

Available modes:
• 'Always Viligant' always stops running when a hostile creature is seen via telepathy.
• 'Original' is standard ToME auto-explore behavior, which ignores telepathy when running or auto-exploring.

• Compatible with ToME v1.6.0

Notes:
Folks who have helped with bugfixes over the years:

• Telepathy will not prevent auto-exploring the way normal sight will. If a halt is triggered by telepathy, hitting auto-explore again will move you at least one more square in the direction of the auto-explore path. If in 'Always Viligant' mode and a hostile is within telepathic sight (but not normal sight), you will auto-explore in 1 square per keypress increments.

Allows Adventurer characters to use some talent trees from addon-provided classes that would otherwise be inaccessible.

More specifically: Adventurers typically are allowed to use talent trees for classes added by addons, unless those classes are flagged as not for use on random bosses. This addon bypasses that check, making talent trees from classes so flagged available to Adventurers.
